The Nintendo 64 has a whole bunch of development hardware used to make games for the Nintendo 64, many of which are quite rare nowadays and very hard to get a hold of. This page will contain a list of the various bits of hardware used on the Nintendo 64.

Note: For the N64 SDK Homebrew section of this website, I will only be using PC/windows hardware so having this hardware is unnecessary for this purpose. This page is for reference only.

Flash Cartridges

These are the only items on the list that are still available for sale. Flash carts allow you to load ROMs onto them so that you can play N64 games on the original hardware rather than depending on an emulator. The good thing about these devices is that they’re still in production so you can buy one if you want. They are a bit costly though.

Everdrive 64

The Everdrive 64 by krikzz is a cartridge with an SD card slot at the top which allows you to play N64 and NES ROMs on your N64 console.

There are various models, but the model 3 is the latest and has a pretty much 100% compatibility with all games that came on a standard cartridge, even ones such as Animal Crossing (japan only) which have a battery for the internal clock. The model 2 has a few more incompatibilities such as Banjo Tooie and Jet Force Gemini which had a custom CIC lockout chip. The model 2 also needs to be restarted in order to register a save onto the SD card while the V3 cannot.

This is the one that I use and it works pretty well for general play and running homebrew ROMs.

64Drive

The 64drive is made over at retroactive.be and can run Nintendo 64 ROMs much like the Everdrive. However, its purpose is more for developers than it is for just loading ROMS. As far as I know, it cannot run NES games or some games like Animal Crossing or Dezaemon. It is also a bit more expensive than the everdrive.

However the big advantage to the 64drive is that it has a USB port on top of the SD/Compact Flash which allows developers to load ROMs onto the device within a few seconds, whereas otherwise you’d need to constantly be switching out SD cards.

Workstations

These are PC-style machines that allow for development environments where you can code for the Nintendo 64.

SGI Indy

Made by Silicon Graphics Incorporated (Makers of the Reality Co-Processor used in the N64), the SGI Indy is a workstation used by many developers for the N64. The official SDK comes with two versions – one for Windows and another for the SGI Indy.

Backup hardware

The backup hardware is sort of the ancient version of Nintendo 64 flash carts. It allows the players to create backups of their cartridges (and upload them to their computer) and even load ROMs for play on the console itself.

Doctor v64

The Doctor V64 by Bung Enterprises is an adapter that plugs into the bottom expansion port of the Nintendo 64 much like the N64DD. Its purpose is to allow the user to load their ROMs to a CD (later models added a port to transfer ROMS with a cable instead of a CD).

CD 64

The CD64 by UFO/Success Company is a backup device that can run ROMs off of a CD. As far as I know, it doesn’t write, only read. It also has a handy port for connecting to a computer that can be used for some development purposes.

Mr. Backup Z64

This bit of development hardware connects through the cartridge port on the top of the N64 require a PC but rather you just plug a cartridge into the machine and copy the ROM onto a zip disk. That’s really all there is to it.

Real-time development hardware

This hardware is used mostly to enable the developer to edit the assets in a ROM while the game is playing. Most of these are used alongside SDK applications like the Monegi Multi Viewer (MMV), NIFF Editor or CITextureEditor for real-time editing of game assets and debugging during playback.

IS-Viewer 64

The IS-Viewer 64 looks like an elongated cartridge with a chunk of circuit board sticking out through the top. It is used in conjunction with some of the applications included in the SDK pack.

Partner N64

This is another development setup that can be used for development and debugging during ROM playback. It can also be used with the MMV, but it appears to have its own SDK included that is as of yet unfound. Not that it would be helpful because you’d actually need the hardware to make the interface work.

The Partner N64 also has two versions – one that connects directly to your pc via an installable card, and another version that is accessible through a LAN.

Monegi Smart Pack

The Monegi Smart Pack (MSP) is another dev system that can be used to do some real-time editing of Nintendo 64 games while the games is running.

I don’t have much information about this, except a Japanese auction that listed the following components and photos.

SN Systems dev kit

This is an alternative SDK for the N64 developed by SN Systems, a company that makes dev kits for many consoles since 1990. What this seems to be is an alternative to the Partner 64, a cartridge that you can connect to interface between the development PC and the real N64 hardware.

Miscellaneous hardware

These are other bits and pieces that don’t really fit anywhere else.

N64 Flash Gang Writer

This is a rare bit of hardware. It doesn’t serve much purpose other than to write ROMs to blank cartridges. It was probably used for distributing to testers or to journalists, since using a device like this would be very clunky and slow. It can copy one donor cart to seven other ones.

As far as I can tell, the only cartridges that were compatible with the Flash Gang Writer are the tall dev ones, not the standard retail cartridges.

SN Systems SN Maestro 64

Much like the SN Systems Dev Kit, this is a cartridge-like bit of software development equipment that allows the developer to pass musical code directly to the N64 console, without having to go through as part of a regular ROM.
